Cost guardrails tame autonomous data agents' runaway bills
Autonomous data agents using LLMs can rack up thousands of dollars per run by scanning terabytes in BigQuery. A developer built cost-safe agents with two guardrails: dry-run scan cost checks and LLM token spend limits. The approach prevents expensive trial-and-error loops common in open-ended analytical queries.

The piece is a practical fix for a real cost problem, but it's narrowly focused on BigQuery and may not generalize to other warehouses or agent frameworks.
